This invention has relation to road grading machines, and it consists in the novel construction und arrangement of parts hereinafter shown and described.

The object of the invention is to provide a machine of the character indicated which is light of draft and of durable structure and consequently cheap to manufacture and economical to operate.

XV ith the above object in view the machine consists `of a skeleton frame, the arts of which are so arranged as to effectue ly Withstand the strain to which such a machine is subjected. The forward portion of the frame is mounted upon a tongue truck and the rear portion of the frame is supported by ground wheels jonrnaled upon an axle which forms n portion of the said frame.

A plow is pivotally attached to one side of the fra me and means is rovided for raising and loweringr the sai plow. A scraper blade is also pivotally attached to the frame and has one end located behind the said plow and is disposed at an acute angle with relation to the line of draft with its other at the said point. A draw bar 11 is connected with the forward ends of the beams 1 and the braces 10 and at its rear end connects with the intermediate portion of the cross bar S. Supporting wheels 12 are journaled upon the axlebetween the points of attachment of the trusses 7 with the said axle and the point of attachment of the beams l there with. A platform 13 is mounted upon the axle 3 between the beams l and is braced at its forward portion bv means of brackets 14 which depend from the arch portions of the said beams l.

A standard 15 is pivotnll)Y connected at its forward end with the cross bar and is provided at its inner side with u bruce 1G which is also pivotally connected at its forward end with said cross bnr. A plow share l'i' is attached to the rear end ot' the said standard and a colter i8 is' fixed at its lower end to the said share 17 and at its upper end to the is a detailed transverse sectional View of n intermediate portion of the standard 15. A line 4 4 1 laterally disposed arm 19 is liked to the shaft is a detailed view of a l -t and at its free end is pivotally connected frame for a suiicient distance to equalize or l compensate for the additional draft caused by tin` presence of the plow :1t the side of the frame. The said scraper blade is located in advance of the rear supporting; wheels` and consequently when the machine is in operation the said supporting` wheels l hure smooth ground to move over. Means i is provided for raising and lowering thej seid scraper blade and snid means may be y so manipulated as to raise one or the other i of the ends of the seid blade Without nil'ecti .inga the opposite end. i In the accom]anyinpr drawings: Figure l is a top plan View of the road grudingmai chine.

by means of a link with the standard 15. An arm 21 is also fixed to the shaft 4. A lever 22 is fulcrumed upon the shaft 6 and is connected with the arm 21 by means of a rod 23. Strips 24 connect the shafts 4 and 5 together and a gear segment 25 is mounted upon one of the stri s 24 and is positioned concentric to the sha t 6. The lever 22 carries a spring actuated pawl 26 which is i adapted to engage the teeth of the ear segment 25. The plow share 17 is oft e usual arrow-head type and its outer edge projects beyond a vertical frame in which the superposed truss 7 lies and consequently the said share projects sutliciently to cut into a bank or the side of a ditch as the machine is used for repairing or rading a road bed. It will also be seen that y reason of the lever mechanism 22 and its connections through the shaft 4 with the standard 15 that means is provided for raising and lowering the share 17 and the colter 18 and that the said parts may be secured in adjusted positions.

A standard 27 is ivotally connected at its forward end with the cross bar 8 and is provided upon one side with a brace 28 which is also pivotally connected at the forward end to said cross bar. A block 29 is fixed to the lower rear end of the standard 27. The block 29 is provided with a pivot bolt 30 which has pivotal connection with a block 31 carried by a scraper blade 32. The shaft 5 is provided with an arm 33 which is pivotally connected with the standard 27 by means of a link 34. The said shaft 5 is also provided with an arm 35. A lever 36 is ulcrumedupon the shaft 6 and is operatively connected with the arm by means of a rod 37. A gear segment 38 is fixed to one of the strips 24 and is positioned concentrica.l with relation to the shaft 6. TheV lever 436 carries a spring actuated pawl 39 which is adapted to engage the teeth of the gear segment 38. A lever 40 is fixed to the shaft 6 and a gear segment 41 is attached to one of the strips 24 and is concentrically ositioned with relation to the said shaft 6.

he said lever 40 carries a spring actuated pawl 42 which is adapted to engage the teeth of the gear segment 41. An arm 43 is fixed to the shaft 6 and is pivotally connected with a standard 44 by means of a link 45.

The forward' end of the standard 44 is pivoted upon the cross bar 8 and the said standard is provided at one side with a brace 46 the forward end of which is also pivotally connected to the crossA bar 8. A block 47 is fixed to the lower rear end of the standard 44 and is rovided with a pivot bolt 48. The pivot olt 48 has pivotal connection with a block 49 also fixed to the rear side of,

the scraper blade 32. The scraper blade 32 is located in advance ofthe rear supportingr wheel 12 and at one end is located approximately behind th'e middle of the plow share ananas i 17 and at its other end projects beyond the `vertical lane of the truss 7 at the opposite side of t e machine. is mounted upon the forward portion of the frame of the machine.

From the above description it is obvious that by swinging the levers 36 and 40 simultaneously that the rear ends of the standards 27 and 44 will move simultaneously and thus the scra r blade 32 may be raised or lowered wit its opposite end portions occupying the same relative position or by swinging either of the levers 36 or 40 while the other lever is permitted to remain at rest one or the other of the ends of the scraper blade 32 will be raised or lowered without affecting or moving the o posite end' portion of the said scraper bladpe. Thus means is provided for tiltlng the scraper blade with relation to the lane of the surface of a road and for adjustlng the said bladevertically with relation 4to the road surface and the position of the plow share 17.

The trusses 7 are of peculiar construction of which the followin is a description. The

'truss consists of renc bars 51 which overof the forwardreach bars 5l and also forni portions of bearing for the ends of the shaft 4. The lower forward ends of the bars 51 join with the ends of the cross bar 8. Brace bars 53 overlap at their forward ends the forward ends of the inclined barsI 52 and also join with the cross bar 8. At their rear ends, the said brace bars 53 receive the end portions of the shaft 6 and are located adjacent the rear ends of the rear reach bars 51. Inclined bars 54 at their upper forward ends are located adjacent the rear ends of the reach bars 55 and also receive the end portions of the shaft 6. IThe lower rear ends of the bars 54 join with the rear axle 3. Brace bars 55 join at their rear ends with the axle 3 and at their forward ends receive the end portions of the shaft 4. Thus it will be seen that the brace bars 53 cross the brace bars 55 and at their point of intersection they are riveted together. The strut bars 56 join with the brace bars 53 and 55 at their point of intersection and at their upper ends the said strut bars form portions of the end bearings for the shaft 5. By this arrangement of parts it will be seen that a skeleton frame-work is effected and that the parts are so disposed as to eliectually brace the entire structure against the strain to which such a machine is subjected during the op; eration of grading or making a. road.

It will be seen that the yparts are so arranged that the draft may be easily divided attheopposite sides of ailineextending An operators seat 50` along the median longitudinal dimension of the machine and that means is provided for eteeting adjustment of the digging and .st-raping members with relation to each other to eteetnally operate upon the sides of the rond or in the ditehes to remove the soil VFrom the ditches and deposit the saine upon the crown of the road.

Having described our invention what we claim as new and desireI to seein-e by Letters Patent. is:
